Contour Lines
 They represent a
change in height
or elevation
 This Map: Every
20 Meters
 Everything
touching the
same line is at the
same elevation
Contour Lines and Elevation
 Imagine if you drew lines
around a mountain

Contour Lines and Elevation
 The closer the contour lines are to each other, the

•Circles Form Around Hilltops/Ridges
•Gaps form Around Valleys/Ravines
Stream or River Contour Lines
 Contour lines that
cross a stream or
river make a V shape
that points up
stream to the water
source that created
the river.
